Answer:
D. CPCTC
Explanation:
THere is a statement column proof given for angle bisector construction.
Statement Justification
Angle MBP is congruent to CPCTC
angle NBP
Since the previous line proved congruence for the two triangles by SSS,
the next step is corresponding angles are equal, by corresponding parts of congruent triangles are congruent
So we have the missing justification as CPCTC
D, CPCTC
